AEC-Q100 Grade 1 6 A synchronous buck converter, 2.95-6 V input, 3×3 mm WQFN-16
The TPS54618C-Q1 is a 6 V, 6 A synchronous step-down current-mode converter with two integrated 12 mΩ MOSFETs, operating from a 2.95 V to 6 V input. The switching frequency is adjustable from 300 kHz to 2 MHz and can be synchronized to an external clock. It provides a 0.8 V ±1% reference, adjustable soft start and sequencing, and a power-good output in a thermally enhanced 3 mm x 3 mm WQFN-16 package. Typical uses include automotive head units, instrument clusters and ADAS cameras.
